Revision eff48ddeab782e35e58ccc8853f7386bbae9dec4 authored by Linus Torvalds on 22 September 2020, 16:08:33 UTC, committed by Linus Torvalds on 22 September 2020, 16:08:33 UTC
Pull tracing fixes from Steven Rostedt: - Check kprobe is enabled before unregistering from ftrace as it isn't registered when disabled. - Remove kprobes enabled via command-line that is on init text when freed. - Add missing RCU synchronization for ftrace trampoline symbols removed from kallsyms. - Free trampoline on error path if ftrace_startup() fails. - Give more space for the longer PID numbers in trace output. - Fix a possible double free in the histogram code. - A couple of fixes that were discovered by sparse. * tag 'trace-v5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: bootconfig: init: make xbc_namebuf static kprobes: tracing/kprobes: Fix to kill kprobes on initmem after boot tracing: fix double free ftrace: Let ftrace_enable_sysctl take a kernel pointer buffer tracing: Make the space reserved for the pid wider ftrace: Fix missing synchronize_rcu() removing trampoline from kallsyms ftrace: Free the trampoline when ftrace_startup() fails kprobes: Fix to check probe enabled before disarm_kprobe_ftrace()
